Correlates of male fitness in captive zebra finches - a comparison of methods to disentangle genetic and environmental effects

Table 1 Additive genetic variance (V_A), heritability (h²) and coefficient of additive genetic variance (CV_A) of traits.

Trait	V_A (SE)	h² (SE)	CV_A (%)
Tarsus	0.19 (0.022)	0.55 (0.046)	2.43
Song rate	0.64 (0.22)	0.26 (0.062)	11.9
Beak colour	0.027 (0.005)	0.33 (0.041)	-
Fitness	0.26 (0.19)	0.38 (0.18)	28.5

V_A of traits is based on tarsus length in mm, the BLUPs of song rate in seconds^1/2, the PC1 of beak colour, and the relative fitness (number of eggs fertilised/mean number of eggs fertilised). The CV_A of traits is based on tarsus length in mm, song rate in square-root seconds, and fitness in number of eggs fertilised. Note that CV_A of beak colour is not computable.
